Item 9. Undertakings.
- ---------------------

(a) The undersigned registrant hereby undertakes:

Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Securities Act") may be permitted to
directors, officers or persons controlling the registrant pursuant
to the provisions described in this registration statement, or
otherwise, SEI Investments Company (the "Company") has been advised
that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is
therefore unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by
the Company of expenses incurred or paid by a director, officer or
controlling person of the Company in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being
registered, the Company will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of
such issue.
